Two Mallards hiding at the water edge.

Mallards
The Mallard (Anas platyrhynchos; Greek for "flat billed duck), also known in North America as the Wild Duck, is a common and widespread dabbling duck which breeds throughout the temperate and sub-tropical areas of North America, Europe and Asia. It also frequents Central America and the Caribbean. It is probably the best-known of all ducks.
This dabbling duck is 56-65 cm length, with an 8198 cm wingspan, and weighs 7501000 g. It is strongly migratory in the northern parts of its breeding range, and winters farther south. It is highly gregarious outside of the breeding season and will form large flocks. They are exceptionally fast flyers for their size, reaching speeds of 65 km/h (40 mph).
The breeding male is unmistakable, with a green head, black rear end and a blue speculum edged with white, obvious in flight or at rest. Males also possess a yellow bill with a black tip, whereas females have a dark brown bill.
The female Mallard is light brown, with plumage much like most female dabbling ducks. It can be distinguished from other ducks, by the distinctive speculum. In non-breeding (eclipse) plumage, the drake looks more like the female.
It is a bird of most wetlands, including parks, small ponds and rivers, and usually feeds by dabbling for plant food or grazing. It nests usually on a river bank, but not always particularly near water.
This is a noisy species. The male has a nasal call, whereas the female has the very familiar "quack" always associated with ducks.
Mallards frequently interbreed with the American Black Duck, Northern Pintail and domesticated species, leading to various hybrids. A Mallard has been recorded as living for 29 years.
The Mallard is one of the rare examples of both Allen's Rule and Bergmann's Rule in birds. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds. Allen's Rule is that appendages like ears tend to be smaller in polar forms, to minimize heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall. Examples of this rule in birds are rare, as they lack ears. However, the bill of ducks is very well supplied with blood vessels and vulnerable to cold.
The size of the Mallard varies clinally, and birds from Greenland, although larger than birds further south, have smaller bills and are stockier.
